1-10 Precautions for Use
CAUTION
Prevent water or foreign objects from getting into the equipment.
Do not let water or foreign objects (e.g., pins or paper clips) enter the
equipment. There is a risk of a fire, electric shock, and breakdown. When such
things accidentally enter the equipment, immediately turn off the power and
unplug the cord. Contact your sales agent instead of trying to disassemble it
yourself.
